Basically, whoever's turn it is posts a screenshot of any PC title and the object of the game is to guess what game it's from. In achieving this, is it then that player's turn to post a shot.

If three days go without so much of a hint or clue, feel free to post another picture even if it's not your turn. If someone guesses it right and doesn't post another picture within a day, anyone's turn.

As a note, it helps to rehost the image if it has the game's name in the image title.
